This is fascinating:

“When a squid ends up chipping what’s called its ring tooth, which is the nail underneath its tentacle, it needs to regrow that tooth very rapidly, otherwise it can’t claw its prey,” he explains.

This was intriguing news ­ and it sparked an idea in Hopkins lab where he’d been trying to figure out how to store and transmit heat.

“It diffuses in all directions. There’s no way to capture the heat and move it the way that you would electricity. It’s just not a fundamental law of physics.”

[…]

The tiny brown batteries he mentions are about the size of a chiclet, and Hopkins says it will take a decade or more to create larger batteries that could have commercial value.

Good advice on buying squid. I like to buy whole fresh squid and clean it myself.

Rough seas are hampering efforts to salvage the boat:

The Speranza Marie, carrying 16,000 pounds of squid and some 1,000 gallons of diesel fuel, hit the shoreline near Chinese Harbor at about 2 a.m. on Dec. 15.

Six crew members were on board, and all were rescued without injury by another fishing boat.

[…]

However, large swells caused by the recent storm caused the Speranza Marie to pull loose from it anchored position and drift about 100 yards from from its original grounded location in Chinese Harbor, according to the Coast Guard.

Researchers have new evidence of how squid brains develop:

Researchers from the FAS Center for Systems Biology describe how they used a new live-imaging technique to watch neurons being created in the embryo in almost real-time. They were then able to track those cells through the development of the nervous system in the retina. What they saw surprised them.

The neural stem cells they tracked behaved eerily similar to the way these cells behave in vertebrates during the development of their nervous system.

It suggests that vertebrates and cephalopods, despite diverging from each other 500 million years ago, not only are using similar mechanisms to make their big brains but that this process and the way the cells act, divide, and are shaped may essentially layout the blueprint required develop this kind of nervous system.

In 1878, a 55-foot-long giant squid washed up on the shores of Glover’s Harbour, Newfoundland. It’s the largest giant squid ever recorded—although scientists now think that the size was an exaggeration or the result of postmortem stretching—and there’s a full-sized statue of it near the beach where it was found.
